Multicast
Samuel Heinrich
Text
Intro
One source speaks.
Many receivers wait.
Not every packet needs
to cross every gate.
Verse
Unicast walks alone,
one path, one name.
Anycast finds the closest,
different route, same flame.
But multicast is listening,
join the group and stay.
Tune into the stream,
let the packets find the way.
Pre-Chorus
I-G-M-P report,
membership in sight.
Layer two is listening
to the group tonight.
Querier asks the question,
who is still alive?
Receivers answer softly,
keep the flow online.
Chorus
Join the group.
Hear the stream.
Multicast inside the machine.
One to many,
not one by one.
Listen in
when the source has begun.
Verse 2
P-I-M moves the signal
through layer three.
R-P knows the source,
knows where it will be.
Rendezvous in the core,
tree begins to grow.
Branches split the traffic
only where it needs to go.
Hook
Membership report.
Join.
Leave.
Query.
Group.
Source.
R-P.
P-I-M.
I-G-M-P.
Bridge
No flood for the silent.
No stream for the blind.
Only those who ask it
get the signal assigned.
From switch to router,
from access to core,
one transmission opens
many doors.
Final Chorus
Join the group.
Hear the stream.
Multicast inside the machine.
One to many,
not one by one.
Listen in
when the source has begun.
Outro
The querier calls.
The members reply.
The R-P remembers
where the sources lie.
